Handler behaviour

Resolves a character option object and calls CEyeControl::SetEyeBallNo, CEyeControl::SetEyeMoveType, or CEyeControl::SetEyeMoveManual.

Encoding

The command header is one 32-bit word, as described in §3 Instruction encoding:

 31            24 23            16 15             8 7              0
+----------------+----------------+----------------+----------------+
|  flags         |  argument byte |  extra words   |  0x33          |
+----------------+----------------+----------------+----------------+

Bits 8–15 give the number of 32-bit operand words that follow. Bits 16–23 are handed to the handler as a bitfield; on character commands bit 0 normally says whether a character selector word is present. Bit 31 is the keep-going bit.

Operand fields

10 documented fields. input fields are read from the command's operand words; derived fields are computed from other fields rather than stored separately.

Field	Role	Meaning
`character`	input	The packed 32-bit character selector word. Its low half is the character id and byte 2 is a secondary class/variant input; see `character_number` and `character_variant`.
`eye_ball`	input	Whether the eye-ball path (CEyeControl::SetEyeBallNo) runs.
`eye_ball_byte`	input	Eye-ball number byte passed to CEyeControl::SetEyeBallNo (low 2 bits); suppressed when zero.
`eye_move`	input	Whether the eye-move path (SetEyeMoveType/SetEyeMoveManual) runs.
`manual_time`	input	Duration, in the units this command uses, for `manual`.
`manual_x_s8`	input	Signed x component for SetEyeMoveManual.
`manual_y_s8`	input	Signed y component for SetEyeMoveManual.
`move_action`	derived	Which eye-movement mode `CEyeControl` is put into.
`move_selector`	input	Selects which `move` the handler acts on.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.
